摘要
江西大余樟东坑钨钼矿属外接触带石英单脉型矿床,含矿石英脉具"上钨下钼"垂向矿化分带规律,近年在矿区深部发现蚀变花岗岩钼(钨)矿化,矿床呈现"上脉下体、上钨下钼"成矿构式。初步分析认为,这一成矿构式是区域构造应力与成矿花岗岩演化耦合的结果,隐伏花岗岩侵位高度是影响石英脉垂向矿化分带的主导要素,蚀变岩脉是矿区花岗岩型钼(钨)矿找矿标志和突破方向。
The ZhangDongkeng Tungsten Molybdenum deposit in Dayu county,Jiangxi province belongs to the quartz lonely vein type of deposit outside contact zones.The quartz vein-bearing mineral is of vertical mineralization distribution regulation,tungsten in the upper and molybdenum in the lower.In resent years,the metamorphic granite type of molybdenum-tungsten mineralization in the deep of the mineral district has been found.The deposit presents a mineralizing structure of ＂upper vein and lower body＂ and ＂upper tungsten and lower molybdenum＂.Further analyses show that it is a result of coupling for area conformation stress and mineralizing granite evolvement.The altitude of the concealed granite approaching is a dominant geological element affecting the vertical mineralization zoning of the quartz vein.The metamorphic rock vein is a symbol of prospecting ore and a direction of breakthrough for the granite body type of molybdenum（tungsten） mineral deposit in the ore district.
